Liv, even though you share a L, could that fellow contact H and tell him he can't unilaterally change the financial arrangements without potentially facing court action? That way, he's protecting H's interests, too. What do you think? I think it matters what the intention of the L is when he relays advice to a client! So, if the L INTENDS to save H the risk of punishment, then he's acting in the client's best interest.

Not a lawyer, but I play one on TV,
